These rugged nuts have a taller base than other wing nuts with more threads to engage for a better hold. They also have a thicker body so they won’t weaken under high stress. Strong enough for use on tanker trucks, they are designed for large, heavy assemblies that need to be opened and closed often. The wings give you more leverage than knurled-head nuts, so you can apply greater torque and achieve a tighter fit.

Twist these thumb nuts into spaces without a lot of clearance. They have a short, slip-resistant head, so you can grip them easily and make controlled adjustments in cramped spots. You can also use them as jam nuts by threading them against another nut to hold it in place.

Twist the slip-resistant head by hand, then insert a T-handle hex key into one of the holes to apply extra torque for a tight fit. Nuts have a low-profile head that fits into cramped spaces. You can also use them as jam nuts by threading them against another nut to hold it in place.
